Abstract
The present invention relates to a process for the determination of an analyte, in which a sample optionally containing the analyte to be determined is brought into contact with a first receptor R1, which has a binding affinity for the analyte, immobilized on a solid phase, and a receptor R2, which likewise has a binding affinity for the analyte, is added and in which furthermore the resulting immune complexes are brought into contact with a binding factor which has a binding affinity for the analyte and for a receptor R3 immobilized on the same or a second solid phase and in which the amount of the analyte bound to the first solid phase or, if present, to the second solid phase is detected in a suitable manner.
